Free Open-Source Tools for Identity, Security, Microsoft 365, Intune, Defender, and Active Directory

One of the most practical ways to contribute to a technical community is to turn repeatable technical knowledge into tools that other professionals can use.

That is the philosophy behind the growing collection of free and open-source tools available through the SAG Business Group Technical Community.

The community currently organizes many of these projects into two complementary families:

Canvas — Assessment, Reporting & Analysis

Atlas — Mapping, Structure & Visualization

Why Community Tools Matter

Modern enterprise identity and security platforms can become extremely complex.

An organization may operate:

·         Active Directory

·         Microsoft Entra ID

·         Microsoft 365

·         Microsoft Defender

·         Microsoft Intune

·         Hybrid Identity

·         PKI

·         Hundreds of applications

·         Thousands of users and devices

·         Privileged accounts

·         Service accounts

·         Managed identities

·         Other non-human identities

Understanding those environments often means gathering information from many different consoles, APIs, scripts, and configuration locations.

Free community tools can help automate that process.

The Canvas Tool Suite

The Canvas Tool Suite focuses on assessment, reporting, and analysis.

ADCanvas — Active Directory

ADCanvas provides Active Directory reporting and analysis across areas such as forests, domains, domain controllers, objects, trusts, Group Policy, and replication.

Project:

https://github.com/SanthoshSivarajan/ADCanvas

EntraIDCanvas — Microsoft Entra ID

EntraIDCanvas creates Microsoft Entra ID documentation and reporting covering users, groups, applications, enterprise applications, Conditional Access, roles, devices, and other tenant information.

Project:

https://github.com/SanthoshSivarajan/EntraIDCanvas

M365Canvas — Microsoft 365

M365Canvas covers Microsoft 365 services including Exchange Online, SharePoint, OneDrive, Teams, security configuration, DLP, and sensitivity labels.

Project:

https://github.com/SanthoshSivarajan/M365Canvas

DefenderCanvas — Microsoft Defender

DefenderCanvas focuses on the Microsoft Defender ecosystem, including Defender for Endpoint, Defender for Identity, Defender for Office 365, Defender for Cloud Apps, security configuration, and threat policies.

Project:

https://github.com/SanthoshSivarajan/DefenderCanvas

IntuneCanvas — Microsoft Intune

IntuneCanvas focuses on device policies, compliance, application deployment, configuration profiles, and enrollment across Microsoft Intune environments.

Project:

https://github.com/SanthoshSivarajan/IntuneCanvas

ZeroTrustCanvas — Zero Trust

ZeroTrustCanvas examines Zero Trust across Identity, Devices, Network, Applications, Data, Infrastructure, and related frameworks.

Project:

https://github.com/SanthoshSivarajan/ZeroTrustCanvas

NHICanvas — Non-Human Identities

NHICanvas focuses on an increasingly important part of modern IAM: non-human identities.

Coverage includes service accounts, managed identities, application registrations, and service principals.

Project:

https://github.com/SanthoshSivarajan/NHICanvas

DelegationCanvas — Active Directory Delegation

DelegationCanvas maps Active Directory permissions, ACLs, and OU delegation to make complex delegated-access relationships easier to understand.

Project:

https://github.com/SanthoshSivarajan/DelegationCanvas

AttackPathCanvas — Identity Attack Paths

AttackPathCanvas focuses on identity attack paths involving privilege escalation, lateral movement, and credential exposure in Active Directory.

Project:

https://github.com/SanthoshSivarajan/AttackPathCanvas

The Atlas Tool Series

The Atlas Tool Series serves a different purpose.

Rather than assessment and analysis, Atlas tools focus on creating point-in-time structural maps of identity and infrastructure systems.

ADAtlas

Maps Active Directory forests, domains, sites, trusts, and supporting services.

https://github.com/SanthoshSivarajan/ADAtlas

EntraAtlas

Maps Microsoft Entra ID tenants, identities, roles, applications, and access relationships.

https://github.com/SanthoshSivarajan/EntraAtlas

M365Atlas

Maps Microsoft 365 services including Exchange Online, SharePoint, OneDrive, Teams, and service configuration.

https://github.com/SanthoshSivarajan/M365Atlas

DefenderAtlas

Maps the Microsoft Defender ecosystem across Endpoint, Identity, Office 365, Cloud Apps, security configuration, and coverage.

https://github.com/SanthoshSivarajan/DefenderAtlas

IntuneAtlas

Maps Microsoft Intune device configuration, compliance policies, application deployments, and enrollment structures.

https://github.com/SanthoshSivarajan/IntuneAtlas

PKIAtlas

Maps Active Directory Certificate Services, including Certificate Authorities, templates, trust stores, and issuance structure.

https://github.com/SanthoshSivarajan/PKIAtlas

IdentityAtlas

IdentityAtlas provides a broader structural view across on-premises and cloud identity systems, showing identities, roles, systems, and relationships.

Canvas and Atlas Answer Different Questions

A simple way to understand the two families is:

Canvas helps you understand the environment.

Atlas helps you see the environment.

Canvas is primarily intended for assessment, reporting, and analysis.

Atlas focuses on mapping, structure, configuration, and relationships without scoring.

Together, they provide complementary views of modern identity and security environments.

Free and Open Source

The Canvas and Atlas projects are provided as free, open-source software under the MIT License.

There is no subscription requirement to use the tools.

The projects can be reviewed, tested, modified, and used by the technical community.

The complete project portfolio can be accessed from the Community page:

https://www.sagbusinessgroup.com/community.html

Or directly through GitHub:

https://github.com/SanthoshSivarajan

As with any community-provided administrative or assessment script, review the source and test it in a non-production environment before wider use.

More Than Individual Scripts

The larger value of a community tool portfolio is not any individual script.

It is reusable technical knowledge.

Every time a complex environment can be automatically collected, documented, mapped, analyzed, or visualized, another engineer can spend less time gathering information manually and more time understanding the environment.

That is one of the most practical forms of community contribution.

Conclusion

Modern Identity and Security environments are complex, but the tools used to understand them do not always need to be expensive or inaccessible.

Through the Canvas Tool Suite and Atlas Tool Series, the community provides free open-source capabilities spanning Active Directory, Microsoft Entra ID, Microsoft 365, Defender, Intune, Zero Trust, PKI, non-human identities, delegation, attack paths, and cross-platform identity architecture.

The objective is straightforward:

Build useful technical tools, make them freely available, and enable the community to learn from them, use them, improve them, and share knowledge forward.
